"The Minuum keyboard, through its simplicity, improves your touchscreen typing. Existing keyboards leave you barely enough screen to interact with your apps, and you can't enjoy typing on them. Minuum eliminates the visual clutter of archaic mobile keyboards by adapting the keyboard to a single dimension." You have to watch the video. This is yet another example of a strength of more open platforms - like Android - that often gets overlooked: the ability to experiment with core aspects of the operating system. Whenever someone says there are no Android-exclusive applications, they conveniently overlook things like this. No other platform has stuff like this, and I certainly miss this experimentation on my 8X.

Actually, I don't have the link handy, but I read an interesting study about how Dvorak layouts don't actually improve your performance over QWERTY ones.

From what I remember, their conclusions were based on rapid and intensive retraining of experienced QWERTY typists. It showed that it took them considerable time and effort just to regain their previous QWERTY typing speed.

That's evidence that it probably isn't worthwhile for companies to retrain all their staff on Dvorak, but isn't exactly a fair comparison of the potential performance of the two layouts. For that they'd need to train people from scratch, with equal time spent on QWERTY and Dvorak.
